Charging the battery
G
Risk of injury
Never charge the battery when it is fitted in
the vehicle unless you are using a battery
charger which has been tested and ap-
proved by Mercedes-Benz. These battery
chargers allow charging when the battery is
fitted. The vehicle electronics may other-
wise be damaged. Only charge the battery in
well-ventilated spaces. As the battery is be-
ing charged, gases can escape and generate
minor explosions. These can injure you and
others and may cause damage to the paint-
work or acid corrosion on the vehicle.
Information about battery chargers which al-
low charging when the battery is fitted can
be obtained from a qualified specialist work-
shop, e.g. a Mercedes-Benz Service Centre.
G
Risk of injury

charging process due to the gases which es-
cape from the battery. Do not lean over the
battery while it is being charged.
